Come on....somebody out there has to have some info about this. Gotta get this finished. How do you get the center support bearing off of a 79 323i to replace it? I have the guibo (flex disc) removed and the driveshaft lowered. What now? It appears the shaft is all one piece up to the bearing and beyond.

Help!

Look inside the u-joint that is right behind the center bearing. There should be a circlip in there, after removing it the rear half of the driveshaft should pull off from the front half. Then the bearing can be pulled off as well.

Hey, I appreciate the input. On my model there is actually a nut that you have to loosen and that thing was a Bas#$%^^&&d! I finally got it removed and in my anxiousness to get the thing out I forgot to mark the relative position of the front side of the shaft to the back portion. Am I screwed or what? Do I need to worry about this or just do the best I can?

I'm pissed.

Not certain, but I wouldn't be too worried about it.

Ideally, the driveshaft should go back together with the two halves in their original orientation to each other.

You'll know whether or not you have a problem as soon as you start driving the car - if there's an imbalance due to having the halves mismatched, it'll usually manifest itself as a vibration that gets worse as the car's speed increases.
